RAZOR.

Speeieationof Letters Patent.

Patented my 19', 180s'.

Application led October 3, 1905. Serial No. 281,132.

i To all whom it may concern:

which the followin is a specification.

My invention re ates most particularly to safety razors and has for its object to. rovide such a razor with a blade having a plurality of cutting edges, that is more than two cutting edges, thus doing awayl with thenecessity of fre uent stro ping, honing or sharpening, or t e using o new blades.

My invention will be fully described hereinafter and the features of novelty will bel pointed out in the appended claims.

Reference is to be had to the accompanyin drawing in which igure 1 is a sectional view of my improved razor; Fig. 2 is an end view of the top plate', Fig. 3 is a face view of the blade; Fig. 4 is a sectional view thereof on line 4 4 ofFig. 3, Fig. 5 is a face view of the bottom late and Fig. 6 is a'vertical section throug the top plate, the blade, and the bottom plate, on the plane indicated by the line 6--6 in Fig. 5.

A represents the handle which is provided with a central bore A having a reduced portion A2; a bottom plate B is secured to or forms part of this handle A, and as shown is` provided at its four sides with teeth B which are so arranged as to serve as a guard to prevent the blade C, when in posi-tion, from cutting the person using the razor. This bottom plate B is further provided with four notches B2, the purpose of which will be more clearly brought out hereinafter. The blade C is provided with notches C corre. sponding to the notches B2 of the bottom plate B and is adapted to be secured in position by a top plate D in the manner. to' be more fully described hereinafter. The blade C as shown is s'uare and has four cutting edges C2, althoug this is not absolutely necessary as the-blade might be triangular in shape with three cutting edges or of a different shape with more than three cutting edges. he top plate D is secured to or forms part of 'a screw-threaded'shank D which is adapted to extend through an `opening C3 in the blade and throu h the reduced ortion A2 and into the centra bore A of the andle A. A nut-.E has a hollow screwthreaded shank E extending therefrom which shank IE is adapted to engage the shank D of the top plate D and thus secure the parts inV position, it being understood that the top late is rovided with projections D3 whic extend) through the notches C of the blade C, and into the notches B2 of the lower plate B. The blade is thus revented from rotating on its axis an is securely held in proper position. p While I have shown a-razor blade with four cutting edges, I wish it distinctly understood that I do not limit myself to this construction asthe said blade may be made for instance triangular in shape with three cuttin edges or said blade may be provided with more than four cutting edges, and it is to be further understood that my claims are intended to cover such structures.

With improved blade 'after one cutting m 'edge has gecome dull, another ed e can be It is tolbe understood that my blade may be used in connection with any suitable handle other than the one shown. It is to be further understood that although four notches have been shown in the blade and in the lower plate and four projections on the upper plate, this construction is `not absolutely necessary as one or more notches in the blade and lower plate and 011e o1: more projections on the upper plate willv answer the same purpose.

In order that all the edges ofthe blade C may be straight and in the same plane when clamped in the holder formedby the plates, B, D, the edges of these plates are straight, and in ordernotwithstanding, to give said blade the proper bending surfaces, the top plate D is provided with radial grooves D4, and the bottom late B with radial ridges or raised portions 3, all running toward the corners. Thus the blade when clamped for use, will have four straight cutting edgesand ridges running radially inwardfrom the four corners. f Various modifications maybe made without de arting from the nature of my invention.

Y claim and desire to secure by Letters Patent: l

. 1.- In a safety razor the combination of a polygonal blade the entire perimeter of which straight and to keep the entire perimeter in the same plane, said clamping members also having diagonal ridges andl grooves respectively to Hex the blade.

2. In a safet razorI a polygonal blade every edge of W 'oh is a cutting edge, and a holder oomprisin opposing members adapted to reoeive the b a de between them, one of sa1d members having grooves or depressions 10 converging toward its center, and the other corresponding ridgesor raised portions, eX= tending inward from points corresponding to the portions of the blades corners.

In testimony whereof, I hereunto sub` scribe my name in the presence of two sub- 15 scribing witnesses.
